This particular size of post is most commonly used to install a post and rail fence. When constructing square post and rail fencing, a 125 X 75mm post and 88 x 38mm rail are most typically used. We supply these posts with either flat or pointed ends, depending on whether you intend to concrete or drive the posts in using a heavy tractor mounted ram or similar.
These fence posts are available in softwood treated timber, either pressure treated or treated to UC4 specification.
Common imperial reference – 5×3 inches
What is UC4 Specification?
The life span of the timber is greatly extended using this treatment method. The timber is kiln dried to below 28% prior to pressure treating. This means that when the high pressure treatment process takes place, because the wood so so dry, far more of the chemical treatment gets absorbed into the wood for greater protection against rot.
